Erection

During the erection stage, the mounting designs and the prescriptions
issued by the Site Engineer must be scrupulously followed. As regards
the stages of scaffolding erection, adhere to local regulations.
The main areas on which to focus attention during the erection stages
follow.

STARTING POINT OF THE SCAFFOLDING

The elements described below must be carefully verified and checked.

Scaffolding bases

An outline of the scaffolding corresponding to the erection plan must
be marked off.
The maximum distance from the building (20 m) must be respected
and checked.
Should this not be possible, with the approval of the project designer or
Works Director, add approach planks to the façade or guardrails even
on the inner side.
Face
Before laying the bases, a suitable face must be prepared of coarse gravel
and/or lean concrete if there are to be heavy loads at the foot, or, more
generally, wooden approach planks must be laid out continuously, leng-
thways along the façade.

Controls at the foot of the scaffolding

It is good practice to at least carry out the following checks at the foot
of the scaffolding:
• Avoid placing more than 2 planks under the base.
• Always rivet the base plates to the planks.
• Check the screwing out of the base plates. Screwing out to a maximum
of 20 cm is recommended. Greater screwing out is permitted as long as
speci c technical veri cations have been carried out or additional cross
bracings are added at the base of the sca olding.
• Check that the faces are level and that they are centered in relation to
the bases.
• Check the correct distribution of loads at the foot of the sca olding,
verifying the consistency, e ciency and proper placement of the distribu-
tion elements placed under the base plates (wooden planks, metal plates,
concrete screw nuts, etc.).
• Check the correspondence between the start of the sca olding uprights
in use against those in the erection design and especially the designs
found in the system Ministerial Authorization Booklet. Should they not
correspond, the technical documentation must be modi ed by modifying
the project or, if necessary, modifying the erection depending on choices
made for the project.
